There is an EVR problem causing the F10 -> F11 upgrade path for esound to break. For example, I have installed
esound-libs-0.2.41-1.fc10.x86_64
esound-debuginfo-0.2.41-1.fc10.x86_64
These did not get changed by "yum update" until I removed them manually with "rpm -e --nodeps". "yum install esound-debuginfo esound-libs" then pulls:
esound-libs-0.2.40-2.fc11.x86_64.rpm
esound-debuginfo-0.2.40-2.fc11.x86_64.rpm
